Horizontal distance travelled by a ball if it's thrown with initial velocity of 20 ms-1 at an angle of 30o is
Correct answer: C. 35.3 m
- A. 24 m
- B. 56 m
- C. 35.3 m
- D. 36.3 m
Explanation
The horizontal distance traveled by a projectile can be calculated using the formula for range: Range = ( Vi2/g ) x sin(2θ), where Vi is the initial velocity, g is the acceleration due to gravity (9.8 m/s2), and θ is the angle of projection.Substituting the given values: Vi = 20 m/s, θ = 30°, we have:Range = ( 202 / 9.8 ) x sin(60°)Calculating the above expression gives approximately 35.3 m, which matches Option C.Options A, B, and D reflect incorrect applications of the formula or calculation errors, such as using incorrect trigonometric values or arithmetic mistakes.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
